Guess My Number!

I am thinking of a two digit number, AB, such that A x B=AB/2, and A+B=AB/4. What is the number AB?

Hi;

Welcome to the forum.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
